ABSTRACT:
In a dynamoelectric generator, a low-resistance electrical contact is provided by using a spring below the rotor slot wedges to bias the wedges against the overlapping retaining rings. This biased contact between the wedges and retaining rings forms a conductive current path for high-frequency eddy currents induced on the surface of the rotor and retaining rings at all operating speeds and at rotor standstill. In addition, the spring reduces gauling between the rotor key slots, wedges and retaining ring.
